Tunnel ram or no tunnel ram...

Should I get parts to make these carbs progressive? They are almost 1:1 now.

As long as you aren’t cruising on the secondary main jets you can leave it.

If you are cruising on the secondary main jets you either need to make it 1:1 and add a power valve in the secondary metering blocks and then make the tune up for the secondaries the exact same as the primaries or you need to get it further from 1:1.


You can do either one.
